A/P autoland needs three a/p channels, why isn't the same criteria used for the AOA indicators? What they really need is 4 AOA vanes so they can dispatch with one unserviceable.
But then using software to correct an inherently unstable design at the extreme of its envelope shows how far the industry has gone away from safety first.
there are only 2 channels on a 73
The 757 and 767 both have 3 channels.
If there are only 2 channels on a 737 A/P how does it do a CAT3 A and B autoland or is this another delegation of certification by the FAA?
